Bike-Guard's Flexi-Combo DLX 1500 is a self-coiling 6-foot cable combination lock made from 15mm-thick braided double-weave stainless steel. It's cut resistant and plastic coated for weather resistance and to protect your bike's finish. The combination lock uses all-metal dials and the combination code is user settable. Plus, should you ever forget it, you can override it with the included key, then reset your lock with a new code. Genius.
